22 6.15. Debug Tab The Debug tab is aimed at software/firmware integrators, to help them at the UART communication layer. The BitPipe Serial API is used to communicate with the BitPipe over UART. This tab can be seen as a tool to deepen understanding of communication, and facilitate troubleshooting of issues that may be encountered while integrating the BitPipe. This tab allows you to see the actual message generation, transmission of a request and reception of a reply. An example is provided to retrieve the BitPipe firmware version. Here are the steps: 1- In the Input Command Data field, enter the following hexadecimal string: Click Generate Message a. The message is displayed in the Generated Message field. 3- Click Send Message a. The message is sent to the BitPipe, a reply should be immediately visible in the Received Reply box below. As can be seen in Figure 20, the binary data exchanged is displayed in hexadecimal notation, with the character representation on the left. This allows easy analysis of message data exchanged. The Message CRC will be computed by the Test Tool, so there s no need to enter it in the Input Command Data. Refer to the BitPipe Serial API documentation for more information. The latest version can be found (here) in the Download section. 22

24 7. Autonomous Mode Demo The Autonomous Mode allows the BitPipe to be used without a controlling Host (or application). You can read more about this operating mode in the BitPipe Cellular modem datasheet. To easily demonstrate how this mode works, a demo back-end has been set up on Briowireless servers. You may configure your BitPipe to use this back-end to test and see how simple it is to configure, monitor and control the BitPipe s IOs. To set-up your BitPipe for this demo, it must be configured with Briowireless server information. This includes setting the MQTT Hostname, MQTT Port and Keep-Alive Interval. For your convenience, this information can easily be configured by following these steps: 1- Open the Autonomous Mode Configuration dialog from the Tools menu 2- In the popped-up dialog, click on Load Demo Config The configuration for the demo is auto-filled in the form. 3- Click on Configure : Figure 21: Autonomous Mode Configuration 24

25 4- Unplug the power supply from the BitPipe 5- Turn the AUTONOMOUS switch to ON, designated by SW1 on the demo board 6- Plug back the power supply in the BitPipe After step 6, the BitPipe should automatically start the Radio and establish a connection to the demo servers. This requires that the APN is configured, and an activated SIM with a data plan is inserted in the BitPipe. See section 6.4 and From the Autonomous Mode Configuration dialog, press Open Web Page to remotely control the BitPipe LEDs intensity, and monitor the actual value of the thumbwheel (potentiometer), in real-time. Note: Changing the Autonomous Mode configuration requires a power-cycling of the BitPipe. Figure 22: BitPipe Dev-Kit Demo Website 25
